No,it does not do any damage to the engine or the drive-train of the vehicle with an
automatic transmission

When slowing to a stop there is a slight jerk without applying the brakes?
The year, make, model, transmission and engine info would help but it is probably the transmission down shifting if the vehicle is an automatic.
If you don't have to shift gears in an automatic then what's the third second first D and OD distinctions really for?
In an automatic the Od allows the transmission to use all forward gears (1st, 2nd, 3rd, 4th) using the 3 position allows the transmission to use gears 1 through 3 and no overdrive(generally recommended for towing). the second gear position allows the transmission to use gears 1 and 2 good for slowing on a hill with a heavy load or trailer. The !st position allows the transmission to use only first gear, ideally for stopping or slowing a heavy load. Shifting into a lower gear will not downshift the trans instintaniously. the transmission will shift down when conditions are ment. But, the trans cannot upshift past that point.
What would cause an automatic transmission to delay downshift when slowing down The transmission allows the rpm's to drop as low as 200 before shifting nearly causing the engine to die?
It's probably the torque converter lockup relay. It could also be the torque converter, but there isn't any way to test this on your own. You'll have to take it to a trustworth transmission shop.
What are the symptoms of automatic transmission failure?
I have a 1999 Dodge Caravan SE, While I am driving things are alright, but when slowing down to a stop the transmission downshift late. What causes thisand is there anything I should be concerned about. Recently, I put some more transmission fluid in . could I have overfilled it?This should help:Complete automatic transmission failure is obvious because the car will not move at all when shifted into forward or reverse. Usually the symptoms of impending automatic transmission failure are not quite as dramatic, and can be inspected by a mechanic to determine if the transmission needs replacing or if there is any chance the problem can be repaired.Delayed ShiftingOne common symptom of automatic transmission problems is delayed shifting when the vehicle is cold, particularly for reverse or first gear. Loss of One GearSometimes one gear will go out entirely while the others still function. If fourth or reverse gear fails, for instance, the vehicle at least can be driven to a shop. Unusual Shifting SpeedsShifting may take place at unusual speeds, earlier or later than it should. The speed where shifting takes place also may keep changing. Noise and JerkingAny noise while shifting is a symptom of automatic transmission failure, and so is rough, jerky shifting. Odd MovementIf the vehicle tries to move while in park or neutral, it most likely has automatic transmission failure. Shift Lever IssuesIf the shift lever is difficult to move, this indicates transmission problems as well.
Why does the transmission clunk when shifting gears?
Are you sure it is the transmission that is clunking? It could be the u-joints on the drive shaft that are making the noise. When the u-joints on the drive shaft are bad, there is an audble clunk when you accelerate and when slowing down (basically the same motions you go through when shifting gears).
What could cause a 1988 Chevrolet Monte Carlo SS stall when slowing down or stopping?
Had a 1995 Cavalier with a similar problem. It was some type of solenoid on the transmission (automatic). Cost about $500 to replace at the dealer.
Why does Astra auto 8v stall when slowing?
If the vehicle has an automatic transmission, then the torque converter clutch is probably sticking. The clutch is controlled by a solenoid, that moves it back and fourth. The clutch material can get stuck to the inside of the converter and stall the engine. Have the transmission flushed, and if the problem persists, then have the solenoid replaced.
What causes your automatic transmission to shift harshly into low gear when slowing down?
Some Chrysler vans have a software update for the trans computer available at the dealer for harsh shifts. Other than that there could be an internal problem.
Why does your car jerk when slowing down?
it jerks because if it is automatic it is goin down a gear
Is it normal that with automatic transmission the engine vibrates when you slow down or stop after high speed run?
Engines do not vibrate unless they starve on air or gas. What might vibrate when you are slowing down is wore brake disks or faulty bearings.
Is it normal to shift an automatic 1987 amc eagle wagon without applying the brake?
Yes on a vehicle of that age it is normal to be able to put in gear with out pressing the brake. I assume you mean down-shifting to a lower gear while slowing down? As with any automatic, when slowing down and shifting to a lower gear, applying the brake is assential, mandatory. This, not only slows down the vehicle and engine, but also, the drivetrain. Slowing the drivetrain makes it possible for the for the lower gear to be accepted at a lower speed. Otherwise, you could severely damage the transmission (unless you have a specially built racing tranmission). In most cases, the driveshaft will break at the universal joint at the end of the transmission resulting in the driveshaft spinning around and your rear wheels running over it, causing more damage. If the driveshaft breaks at the rearend the vehicle will just slow to a stop, through break action. Usually, you want to slow the vehicle down to below 40 mph to shift into 2nd gearthen, slow down to 15 mph to shift to 1st gear. However, when going forward from a lower gear to an upper gear, you naturally want to keep the revs up and shifting into an upper gear will cause you to go faster. No breaking is applied. Also, periodic use of all the gears say, 1st, up to and through 3rd, is better on the transmission and helps it to last longer. Good luck! Gears4Go
